    Study Notes

    Computer Systems Overview

    • Basic Structure: Consists of core components including CPU, motherboard, and power supply within a protective case.
    • Peripherals: Devices connecting to the core unit, enhancing functionality, such as monitors, keyboards, and storage devices.

    Computer Associated Peripherals

    • Definition: Any device not integral to the core architecture but connects to it, enabling additional tasks.
    • Examples:
      • Mouse and Keyboard: Input devices for user interaction.
      • Monitor: Displays visual output.
      • Printer: Produces hard copies of digital documents.
      • RAM and DVD-ROM: Storage devices aiding in memory and data retrieval.

    Memory Classification

    • Primary Memory:
      • Random Access Memory (RAM): Volatile memory used for temporary data storage; categorized into SRAM and DRAM. Data is lost when power is off.
      • Read-Only Memory (ROM): Non-volatile memory that retains data; used for essential programs like system boot processes. Types include MROM, PROM, EPROM, EEPROM.

    Secondary Storage Devices

    • Definition: Non-volatile storage enabling permanent data retention beyond primary storage (RAM).
    • Examples:
      • Solid-State Drives (SSDs), Hard Disk Drives (HDDs), CD/DVD/Blu-ray drives, USB flash drives, and cloud services (e.g., Google Drive, AWS).
    • Purpose: Used for backups, archiving long-term data, and storing non-critical information.

    System Configuration

    • Definition: Describes the hardware, software, and processes comprising a computer system, along with their interactions.
    • Components: Includes specific devices, operating system settings, and software in use.

    Programming Languages

    • Machine Language: The fundamental language understood by computers; offers direct control but is tedious for humans.
    • Assembly Language: Low-level programming language closely aligned with machine code, requiring an assembler to translate into executable code.
    • High-Level Languages (HLL): Such as C, FORTRAN, and Pascal, which are more accessible for programmers and abstract away hardware specifics.

    Development Workflow

    • Users write programs in high-level languages.
    • Compilers convert these programs into assembly language.
    • Assemblers translate assembly language into machine code, completing the programming cycle.
